Hey guys my 2.3L cavy is in shambles right now I need to fix it, when the car is started is sounds like a lawn mower and when you try to drive it you go no where unless you slowly press the gas pedal and so I figure maybe it was something with the fuels system, my friend thinks it's the fuel pressure regulator, let me know what you guys/girls think!!

i have the same problem with my 2.4 and i am trying to figure it out have been for along time now for like almost a year still havent figured it out but when the motor warms up it does just fine so if u find out something let me know

Nathan,
I didn't see any particular year in your profile, but that's usually an indication of the temp sensor to the PCM being bad. If it runs fine when it's hot, and not wnen it's cold then the PCM thinks it's hot all the time. When it's cold the PCM uses a default setting for injector modulation, timing..etc but when it's hot it will go into closed loop mode and use feedback from the O2, temp sensor..etc.
